Another interaction-related one.
While looking for a hotel from a big chain, Alice's computer usually
warns her that the map provider's web site has an SSL-related
mismatch. Alice has gotten used to this, and goes through the
interaction without actually reading the dialogue that is displayed
to her. While browsing the search results that the hotel chain
displays, she becomes suspicious, and wonders what warning she
really clicked away.
Motivates: scope of security decisions and context; past security
decisions become context for future ones.
(And yes, this is very close to the actual interaction with a major
American hotel chain.)
Cheers,
